Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly, in particular to a deformable bolt clamping tool. Background Art

[0002] In the charging pile and other mechanical assembly industries, bolts are often needed to connect two parts to meet the needs of product assembly or disassembly. Usually, one end of the bolt is a nut and the other end is a nut. When using a fastening tool to tighten or loosen one end, the other end must be fixed, otherwise the two ends of the bolt will rotate synchronously and cannot be tightened or disassembled.

[0003] However, bolts are often found inside products, where space is limited, narrow and compact, and there are many other parts of the product around them, which will block or hinder the operation of bolt clamping tools. Although there are many standard clamping tools on the market, they are either special-purpose and have a small scope of application, or inconvenient to operate and cannot be inserted into the restricted space to disassemble and install bolts. These tools cannot meet the purpose of clamping bolts of different products and different positions, and cannot play the maximum operation effect. Utility Model Content

The threaded hole is arranged along the radial direction of the handle sleeve and is connected to the mounting hole. The set screw extends into the mounting hole through the threaded hole to tighten the handle, so as to achieve a fastening connection between the handle and the handle sleeve.

[0010] Furthermore, the limit clamping device includes semicircular positioning countersunk holes and limit pins that are embedded in each other. Semicircular positioning countersunk holes are provided on the handle adapter hole and the clamping head adapter hole, and are evenly distributed around the inner ring surface of the handle adapter hole or the clamping head adapter hole.

Finally, insert the handle sleeve 1 into the handle 2, adjust the exposed length of the handle sleeve 1, and tighten it with the set screw 3 to complete the assembly of the clamping tool. The bolt clamping tool of this embodiment is transformed into Fig.15 In the structure shown, the long axis 42 of the bent rod is connected to the handle 2, and the short axis 41 of the bent rod is connected to the clamping head 5.
